Terrestrial carbon management options.

management of terrestrial C pool	sequestration of C in terrestrial pool
reducing emissions	sequestering emissions as SOC
eliminating ploughing	increasing humification efficiency
conserving water and decreasing irrigation need	improving soil aggregation
using integrated pest management to minimize the use of pesticides	deep incorporation of SOC through establishing deep-rooted plants, promoting bioturbation and transfer of DOC into the ground water
biological nitrogen fixation to reduce fertilizer use
offsetting emissions	sequestering emissions as SIC
establishing biofuel plantations	forming secondary carbonates through biogenic processes
biodigestion to produce CH4 gas	leaching of biocarbonates into the ground water
bio-diesel and bioethanol production
enhancing use efficiency
precision farming
fertilizer placement and formulations
drip, sub-irrigation or furrow irrigation
